Curated OER
Why Doesn't SSA Work?
Students investigate the relationship between angles and their sides. In this geometry lesson, students prove why SSA does not work as a true angle side relationship theorem.
Curated OER
Dissecting the Cube
Students investigate the volume of cones. In this geometry lesson, students define the formula to find the volume of cones. They define the concept of having to dissect a three dimensional figure and find the volume.
Curated OER
Distance Formula
Students calculate the distance between two points using the distance formula. In this geometry lesson, students derive the distance formula using the Pythagorean Theorem.
Curated OER
Anything I Can Do You Can Do Better
Students complete a two-week unit involving design and construction concepts. They watch a PowerPoint presentation about geometric shapes, draw the fourteen shapes incorporated in bridge construction, and in small groups design, build,...
Curated OER
Polly and the Shapeshifter
Students analyze the patterns in polygons and relate it to the rate of change. In this algebra lesson, students discuss the relationship between the data and the graph of the data.
Curated OER
The Window Problem
Students identify patterns and compute formulas to solve the problems. In this algebra lesson, students come up with a rule given a pattern, and analyze the relationship between data and graphs.
Curated OER
The Tangent Ratio
Students calculate the tangent ratio given a right triangle. In this trigonometry lesson, students use a right triangle and the Pythagorean Theorem to solve problems.
Curated OER
Which Triangles are Right
Students apply properties of right triangles to solve problems. In this geometry lesson plan, students identify axioms and theorems using examples.
Curated OER
Origami Cube
Students compare two lengths using the area of a square. In this geometry instructional activity, students solve problems using ratio and proportion of the two shapes. They solve equations by taking the square root of both sides.
Curated OER
JFK Assassination
Learners write equations of a line. In this algebra lesson, students investigate the assassination of JFK through linear equations. They calculate the length of given line segments.
Curated OER
Analyzing Graphs and Data
Students collect and analyze data. In this statistics lesson, students graph their data and make inferences from the collected data. They display their data using graphs, bar graphs, circles graphs and Venn diagrams.
Curated OER
Angle Pairs
Students practice identifying right, vertical, and adjacent angles using a Smartboard. They then determine measurements of all of the angles when only one measurement is given.
